Key points at a glance
- Define factor, groups and quantitative outcome.
- Check independence, spread and model diagnostics.
- Report the overall test, effect size and suitable follow-ups.
Frame one comparison question
Example: Does mean task time differ across three learning formats? Format is the factor and time the outcome. If the same people experience every format, a repeated-measures design is needed rather than the basic independent-groups ANOVA.
Examine assumptions
Inspect independent observations, unusual values, within-group distributions and variance differences. When variances differ substantially, Welch’s ANOVA may be more appropriate. A single normality p-value cannot decide the whole analysis for you.
Separate the omnibus test from follow-ups
Report group means and spread, F with degrees of freedom, p-value and an effect-size measure. If your question concerns specific pairs, use planned contrasts or suitable adjusted post-hoc comparisons. Many unplanned t-tests increase error risk.
Interpret the size and design
A detectable mean difference may be small in practical terms. Examine intervals and alternative explanations. ANOVA on observed groups alone does not show that the learning format caused the outcome.
Final submission context
Formal details can feel like a separate writing task, but they matter just as much for a printed submission. Anything missing, misplaced or inconsistently formatted in the document will also appear in the bound copy.
Use this guide together with your cover page, table of contents, page numbers, source notes and appendices. Prepare the final PDF for printing and binding only after the complete file has been checked.
Practical check before PDF export
- Do headings, chapter structure and page numbers match?
- Are sources, figures and tables included completely?
- Are required elements such as declarations, appendices or the cover page included where required?
- Did you open and check the final PDF after exporting it?
Checklist
- Independent versus repeated groups identified.
- Assumptions and variant considered.
- F, degrees of freedom, means and effect reported.
- Follow-ups justified.
Common mistakes
- Assuming F identifies the differing pair.
- Running numerous unplanned t-tests.
- Inferring a causal treatment effect from observed groups.

Frequently asked questions
When use ANOVA instead of a t-test?
For an appropriate quantitative outcome across more than two independent groups.
Does significant F identify the groups?
No. Use appropriate follow-up comparisons.
What if variances differ?
Consider a method such as Welch’s ANOVA and compatible comparisons.
